NETA Level 2 Certified Assistant Electrical Testing Specialist 認定 NETA_2 試験問題 (Q11-Q16):

質問 # 11
On an electrical schematic, adot on a current transformer symbolindicates:

正解：D

解説：
The dot convention indicatespolarity, showing the instantaneous current direction relationship between primary and secondary windings. Correct polarity is critical for protection schemes, differential relays, and metering accuracy. NETA Level 2 technicians must verify CT polarity during installation and commissioning to ensure correct relay operation.


質問 # 12
Shown below is a current transformer with multiple secondary taps. What is the calculated voltage between tapsX1 and X3when200 Vis applied across the full secondary windingX1 to X5?

正解：B

解説：
The voltage developed across a portion of a CT secondary winding is proportional to the number of turns between the selected taps. If 200 V is applied across the full winding from X1 to X5, and the diagram shows that taps X1 to X3 represent 30% of the total turns, then the voltage across X1-X3 is:
200 V × 0.30 =60 V
NETA Level 2 technicians must understand tap relationships during saturation testing, ratio testing, and troubleshooting CT secondary circuits. Incorrect assumptions about tap voltages can result in inaccurate test results or insulation damage during testing.


質問 # 13
During charging of lead-acid batteries, whichexplosive gasmay be generated?

正解：C

解説：
Hydrogen gas is produced during battery charging due to electrolysis of water in the electrolyte. Hydrogen is highly explosive at relatively low concentrations. NETA Level 2 technicians must ensure adequate ventilation, eliminate ignition sources, and follow battery safety procedures during testing and maintenance.


質問 # 14
What is themaximum allowable deviationbetween resistance measurements on bolted electrical connections?

正解：A

解説：
NETA standards allow a maximum deviation of50%between comparable bolted connection resistance measurements. Deviations beyond this threshold may indicate loose hardware, corrosion, contamination, or improper installation. NETA Level 2 technicians must identify abnormal readings and recommend corrective action.


質問 # 15
A ground conductor is routed through azero-sequence current transformer (CT)together with the phase conductors feeding the load. What is the most likely result?

正解：C

解説：
Zero-sequence (residual) ground-fault detection works by measuring thevector sum of currentspassing through a CT window. Under normal conditions, the three phase currents sum to approximately zero. If a ground fault occurs, the return current path bypasses the CT window, producing a net residual current that the CT detects.
If theequipment grounding conductor(or neutral/ground return conductor, depending on the scheme) is incorrectly passed through the same CT window along with the phase conductors, the ground-fault return current can be "captured" by the CT. This causes the residual sum to approachzero, even during an actual ground fault-meaning the protective function mayfail to operate.
NETA Level 2 technicians are expected to recognize correct CT installation practices, especially during commissioning and acceptance testing of ground-fault protection schemes. This includes verifying CT polarity, conductor routing, window CT content, and proper secondary wiring before performing injection or functional trip tests. Misrouting conductors is a classic cause of non-operational ground-fault protection.
